Abstract:
An electronic circuit adapted to drive a display panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a first circuit, a second circuit, a first switch circuit and a control circuit. The first circuit generates display driving signals for driving the display panel. The second circuit receives fingerprint sensing signals from the fingerprint sensors. The first switch circuit is coupled to a second switch circuit on the display panel. The control circuit generates control signals for controlling the first switch circuit and the second switch circuit, so as to control the electronic circuit to transmit the display driving signals from the first circuit to the data lines through the first and the second switch circuits in a first time interval, and control the electronic circuit to receive the fingerprint sensing signals from the fingerprint sensors through the first and the second switch circuits in a second time interval.
